We present a mode-locked ytterbium fiber laser with a higher-order mode fiber compensating the group-velocity dispersion and partially the third-order dispersion of the single-mode fiber at a wavelength of 1 μm . The generated pulses had an energy of 0.5 nJ and could be dechirped externally to a pulse duration of less than 60 fs . The power spectrum shows a spectral full width at half-maximum of 57 nm.
